Quality of Competition - the measure of the quality of opponents a skater faces. QoC is calculated via either weighted scoring or corsi of a players opponents

Relative corsi - A players cosi rating versus the rest of his team. Calculated by subtracting the team's collective corsi rating while he's off the ice from his on-ice corsi rating. Can be used to calculate the relative corsi rating of his opponents for qality of competition purposes

Cowbell - A facet of the game or a skill that a coach/GM overemphasizes in terms of importance to winning. See: Brian Burke and "truculence"

Wayne Gretz - The Nations sites Evil Overlord. Well known for erratic behavior and nonsensical raving. His mental disturbances manifest in his Oilers fandom.

If I recall correctly, PDO is calculated by adding the team shooting percentage while a player is on the ice with the goalie's save percentage while the player is on the ice. On average, it should trend toward 100 (100 being what you would get if you added the entire league's shooting and save percentages together). If it's high or low for a short period (less than two seasons) it generally indicates either good or bad luck for that player. If it's consistently high or low (multiple seasons) it can potentially be indicative of a player's skill level, with very good players having a higher PDO and very bad ones having a lower PDO.

To expand on SOV's post, the reason that we concentrate on that number is that there is a very strong correction back to 100 over time, both at the individual and team level, with a particular regression for teams. With that in mind, I tend to be very sceptical of a team or player that achieves good EV results just via the percentages, since there's little evidence that teams in particular can have that work for them on a repeating basis. There are players that can have high SH% numbers for extended periods, but those gents aren't nearly as common as one might think. Volume outshooting shows some decent evidence of being a repeatable skill, both for players and teams. Percentages, or the bounces if you will, are much more random. The trick is to not be confused into thinking a team or player is better or worse than they really are just because of a run of luck.

The example that I might use from last year was Colorado. They had a very high team SH% and SV% through the first 60 games of 09/10. That gave them out-scoring results that wouldn't have matched their ability to drive possession. To listen to a few of Colorado's fans, one might have thought they'd invented a new way to play hockey. They hadn't, of course, and when reality set in toward the end of last year and this year, their results plummeted. Dallas and Anaheim had that sort of mojo working for them this season. Boston had it in 08/09 and this year. The Flames had it in spades from late December to early March this year, as well as the first two months of 09/10.
